To prepare for the mobile issues work, we will need to setup some feature flagging which separates 2 different treatments for page issues. We will not worry about cached HTML right or FOUC right now, nor will we worry about the new design treatment (tracked in T191303)
In group control or A (which should show for 100% of users by default):
In group B (which should be set to 0):
= Acceptance criteria
 Add a feature flag with control, A and B groups. When group control or A is present show the existing design. When group B is present show the page issue without the design treatment
 The client should decide whether to enter group A or B
 It should be possible to enter group B on reading web staging or a local machine, but impossible to enter the group on production.
= Developer notes
Do not worry about flash of unstyled contents. The purpose of this task is to get a sense of how much of a problem these are and provide us a space to maintain 2 versions of page issues.
= Testing criteria
